In an article about the Vatican II Council’s teaching about the liturgy of the Mass,
Fr. Joseph Fessio writes:
….So, I called this wonderful rabbi in Manhattan and we had a long conversation. At the end, I said, “I want to bring some focus to this, can you give me any idea what it sounded like when Jesus and his Apostles sang the Psalms?” He said, “Of course, Father. It sounded like Gregorian Chant. You got it from us.”
I was amazed. I called Professor William Mart, a Professor of Music at Stanford University and a friend. I said, “Bill, is this true?” He said, “Yes. The Psalm tones have their roots in ancient Jewish hymnody and psalmody.” So, you know something? If you sing the Psalms at Mass with the Gregorian tones, you are as close as you can get to praying with Jesus and Mary. They sang the Psalms in tones that have come down to us today in Gregorian Chant.
So, the Council isn’t calling us back to some medieval practice, those “horrible” medieval times, the “terrible” Middle Ages, when they knew so little about liturgy that all they could do was build a Chartres Cathedral. (When I see cathedrals and churches built that have a tenth of the beauty of Notre Dame de Paris, then I will say that the liturgists have the right to speak. Until then, they have no right to speak about beauty in the liturgy.) But my point is that at the time of Notre Dame de Paris in the 13th century, the Psalms tones were already over a thousand years old. They are called Gregorian after Pope Gregory I, who reigned from 590 to 604. But they were already a thousand years old when he reigned. He didn’t invent Gregorian chant; he reorganized and codified it and helped to establish musical schools to sing it and teach it. It was a reform; it wasn’t an invention. Thus, the Council really calls us back to an unbroken tradition of truly sacred music and gives such music pride of place….
